APPARATUS FOR TREATING GRAIN.

Specification of Letters Patent.

Patented May 26, 1908.

Application filed September 6, 1907. Serial No. 391,661.

To all whom it may concern:

Be it known that I, WILLIAM F. CARLTON, a citizen of the United States, residing at Advance, in the county of Stoddard and State of Missouri, have invented a new and useful Apparatus for Treating Grain, of which the following is a specification.

This invention relates to apparatus for treating grain, and has for its principal obj ect to rovide means for the drying of the grain and) the detaching of any impurities while the grain is in motion, so that the grain will be whitened, its flavor improved and the deterioration due to heating from the presence of moisture will be avoided.

A further object of the invention is to provide an apparatus of this type in which pro- ,vision is made for forcing jets or blasts of dry air through the grain while the latter is in motion.

With these and other objects in view, as will more fully hereinafter appear, the invention consists in certain novel features of construction and arrangement of parts, hereinafter fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the form, proportions, size and minor details of the structure may be made without departing from the spirit or sacrificing any of the advantages of the invention.

The accompanying drawing is an elevation partly in section illustrating an apparatus constructed in accordance with the invention.

The drawingillustrates two forms of conveyer casings, the lower approximately horizontal casing 10 being arranged for the reception of a screw conveyer of any ordinary construction, and the whole or ground grain is delivered from the casing 10 to a second casing 12 which, in the resent instance, is arranged vertically and t e whole or ground grain is carried up through this casing by a endless conveyer 13. l

At a convenient point is arranged a storage tank 15 having a safety valve 16 and air under pressure is forced into this reservoir from a suitable blast fan 18.` From the reservoir lead ipes 19 in which are arranged controlling va ves 20, and each of these pipes 19 is connected to a series of distributing pipes 21, each having an independent valve 22. to the conveyer casings at equidistant intervals throughout the entire length of such casings and in such manner as to direct into said casings currents-of air under any desired pressure, care being taken that the airis thoroughly dried, so that it may absorb any moisture in the grain.

The air is forced into the colunm of grain while the latter is in motion, and each particle of grain will travel ast all of the distributing pi es and will be t oroughly dried, while any a herent foreign matter will be separated and driven 0H so that the grain will be thoroughly cleaned and in the case of ground grain in the form of meal and flour, the effect will be to whiten the grain, especially Where the air is mingled with some bleaching agent, or, if desired, the bleaching agent may take the place of air.

I claim:-

1. In a grain treating apparatus, a conveyer casing, a conveying means therein, a series of liuid discharging pipes connected to the casing at equi-distant intervals throughout the entire length of the latter, means for forcing iiuid under pressure through said pipes, and a separate controlling valve for each ofthe pipes.

2. In an apparatus for treating grain, a conveyer casing, a conveyer therein, a series of liuid distributing pipes connected to the casing at equi-distant intervals throughout the entire length of the latter, each of said pipes having a separate controlling valve, a

uid pressure reservoir, a main pipe extending therefrom and connected to all of the distributing pipes, and means for forcing fluid under pressure into said reservoir.

3. In grain treating apparatus, a pair of superposed conveyer casings arranged in approximately horizontal planes, screw conveyers in said casings, a vertical conveyer casing connecting the superposed casings and arranged to deliver the grain discharged from one to the entrance end of the other, an endless bucket conveyer in the vertical casing, a series of fluid su ply pipes arranged parallel with the severa casings, distributing pipes The distributing' pipes 21 are connected leading from the supply pipes and connected In testimony that I claim the foregoing as to the oasings at equi e distant intervals my own, I have hereto aHiXed my signature throughout'the entire lengths of the latter, a in the presence of two Witnesses.

separate Valve on each of the distributing WILLIAM F. CARLTON. 5 pipes, and a Huid pressure reservoir to which Witnesses:
